I posted previous DynoJet runs, but this one confirms the gains we get from a Eurotoys Supercharger pulley without a tune.

The first run (506 WHP) is a stock 2014 V8 S plus pulley with no tune. Comparing to my no-pully stock run, the SC pulley added +19 WHP (peak). All the gains were above 3750 RPM with +31 WHP/+30 ft-lbs (max WHP delta) occuring at 5800 RPM, exactly as advertised by EuroToys.

The last two runs added a Racechip GTS Black on Map 7 for 554 WHP/520 Ft-lbs (peak). Max HP delta was +76 WHP. That's +20 WHP/+20 Ft-lbs above my no pulley Dyno on Map 7. Using the 15% rule for RWD gives roughly 638 BHP.

You cannot run a lower pulley without a tune. CEL everywhere and way too lean.... but whatever you say

 

 

This is a 2014 V8S. Ignore the green (tune only), the red is the baseline....

 

So you say you got 487rwhp from a totally stock V8S? Edit question for Jimlights obviously

 

Now, unlike previous low-effort attempts this thread is a respectable technical trolling effort.

 

A supercharger pulley is not a lower pulley. You are confused with a crank pulley.

 

OK, no point discussing any of this since every time there is an objection, things get edited to ones convenience. This thread is a waste. Whatever you say, so long as it makes you happy and enjoy your F-Type.

 

 

Also, let's just reports facts as they are, Eurotoys claims 30HP at the flywheel... not +31WHP as you claim (even if it was the upper pulley as now edited)

"This smaller supercharger pulley will give your Jaguar 5.0L a modest power improvement of approximately 30+HP @ the flywheel. The Pulley should be added along with ECU Tuning for a major power gain".

You have no baseline on your dyno to make any type of comparison or analysis.

 

Bye

 

Already posted the baseline. It's been discussed at lenghth. Search tool.

 

Fake Dyno.

Red torque doesn't criss-cross with red HP at 5252.

You're dismissed.

You are assuming that you are communicating with individual that is interested in establishing understanding instead of getting a reaction out of you. Your assumption is not reasonable.

 

 

 

 

Add a new Porsche GT3 to the "blew the doors way, way off" list. Poor guy lined up with me four times with his brand new Volkswagon, still had temp tags. 85 speed limit, private highway, not patrolled AFAIK. The V8 S left him like he was standing still. In fairness, the GT3 is not super expensive. His blonde chick looked newer than the car. She wanted me so bad. He waved himself off politely. Good dude. Observations:

Runs were from approx 75 to 130, no doubt the worst place for his 339 ft-lb VW motor.

Jag +130 WHP (+31%)
Jag +180 Ft-lbs (+53%)
Jag +2 Cylinders
Jag +1L displacement
Jag 267 pounds lighter
Jag 110 lb girl lighter
Jag 20+ car lengths ahead before mercy
Jag vert top-down
Both RWD
Porsche sounded like a Shop Vac

In fairness, not fair.

 

I see that now, thanks. Apologies... I take it thats some motor on a bench since its measuring crank. So not a V8 S.
